This should not be necessary with IEEE 802.1X/RADIUS IP assignment
because IEEE 802.1X authorization has to be completed before DHCP can be
used. Thus, the AP already knows the assigned IP address before needing
to reply to any DHCP requests. If RADIUS server decides to change the
assigned address during re-authentication, this might be more relevant,
but that does not sound like a common case.
